K8S

K8S部署

先创建一个debian模板

选择iso

快速安装一下即可：

安装完成克隆成模板：

Master节点

直接克隆一个就可以

克隆两个本地node

sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list.d/debian.sources
sed -i 's|security.debian.org/debian-security|mirrors.ustc.edu.cn/debian-security|g' /etc/apt/sources.list
echo "export PATH=$PATH:/usr/sbin:/home/$(whoami)/.local/bin" >> ~/.bashrc
source ~/.bashrc
apt install ufw

apt install sudo vim wget curl -y

sudo hostnamectl set-hostname dayi-cloud-k8s-master

这里HOSTS用了tailscile 来进行相互访问

curl -fsSL https://tailscale.com/install.sh | sh

这样就配好hosts了

dayi-cloud-k8s-master
dayi-cloud-k8s-node1
dayi-cloud-k8s-node2

Master

sudo ufw allow 6443/tcp
sudo ufw allow 2379/tcp
sudo ufw allow 2380/tcp
sudo ufw allow 10250/tcp
sudo ufw allow 10251/tcp
sudo ufw allow 10252/tcp
sudo ufw allow 10255/tcp
sudo ufw reload

cat <<EOF | sudo tee /etc/modules-load.d/containerd.conf 
overlay 
br_netfilter
EOF

sudo modprobe overlay 
sudo modprobe br_netfilter
cat <<EOF | sudo tee /etc/sysctl.d/99-kubernetes-k8s.conf
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1 
net.bridge.bridge-nf-call-ip6tables = 1 
EOF


sudo sysctl --system

Other

sudo ufw allow 10250/tcp
sudo ufw allow 30000:32767/tcp
sudo ufw reload


cat <<EOF | sudo tee /etc/modules-load.d/containerd.conf 
overlay 
br_netfilter
EOF

sudo modprobe overlay 
sudo modprobe br_netfilter
cat <<EOF | sudo tee /etc/sysctl.d/99-kubernetes-k8s.conf
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1 
net.bridge.bridge-nf-call-ip6tables = 1 
EOF


sudo sysctl --system

SSH-密钥复制

mkdir ~/.ssh
echo "ssh-rsa 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 root@dayi-cloud-k8s-maste" >> ~/.ssh/authorized_keys

安装containerd

apt install containerd
containerd config default | sudo tee /etc/containerd/config.toml >/dev/null 2>&1
sudo vi /etc/containerd/config.toml

scp /etc/containerd/config.toml dayi-cloud-k8s-node1:/etc/containerd/config.toml
scp /etc/containerd/config.toml dayi-cloud-k8s-node2:/etc/containerd/config.toml

sudo systemctl restart containerd
sudo systemctl enable containerd

安装K8S仓库


sudo apt install gnupg gnupg2 curl software-properties-common -y
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo gpg --dearmour -o /etc/apt/trusted.gpg.d/cgoogle.gpg
apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main"

安装K8S

apt update
apt install kubelet kubeadm kubectl -y
apt-mark hold kubelet kubeadm kubectl

初始化集群：

kubeadm init --image-repository registry.aliyuncs.com/google_containers --pod-network-cidr=10.234.0.0/16 --control-plane-endpoint=dayi-cloud-k8s-master --v=5

K8S2

哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈

换CENTOS

换大牛

Rencher

真男人直接下载：

修改主机名：

ssh-keygen -t ecdsa -b 256
ssh-copy-id node1
ssh-copy-id node2

复制密钥：

ssh-copy-id node2

复制hosts

scp /etc/hosts root@node1:/etc/hosts 
scp /etc/hosts root@node2:/etc/hosts

修改内核配置

/etc/sysctl.conf

vi:

echo -e 'net.bridge.bridge-nf-call-iptables = 1 \nnet.bridge.bridge-nf-call-ip6tables = 1' >> /etc/sysctl.conf

开启模块

modprobe br_netfilter
ls /proc/sys/net/bridge/
echo "br_netfilter" > /etc/modules-load.d/br_netfilter.conf
sysctl -p

发送到从节点：

scp /etc/sysctl.conf root@node1:/etc/sysctl.conf
scp /etc/sysctl.conf root@node2:/etc/sysctl.conf 

#从节点执行：
modprobe br_netfilter
ls /proc/sys/net/bridge/
echo "br_netfilter" > /etc/modules-load.d/br_netfilter.conf
sysctl -p

防火墙 SELINUX：

systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld



setenforce 0
vi /etc/selinux/config
#修改： SELINUX=disabled

reboot

发送到从节点

scp /etc/selinux/config root@node1:/etc/selinux/config
scp /etc/selinux/config root@node2:/etc/selinux/config

查看SELINUX状态

sestatus

NTP时间同步
